Abstract

The invention relates to a compound dehumidification system based on transcritical carbon dioxide heat pump regeneration. The compound dehumidification system comprises a transcritical carbon dioxide heat pump and a dehumidification rotating wheel. Wet air is condensed and dehumidified through the cold end of the transcritical carbon dioxide heat pump, enters a dehumidification area of the dehumidification rotating wheel, is subjected to adsorption dehumidification and then is discharged; regenerated air is heated by the hot end of the transcritical carbon dioxide heat pump and then enters a regeneration area of the dehumidification rotating wheel to realize regeneration of the moisture absorbent. The invention further relates to application of the composite dehumidification system based on transcritical carbon dioxide heat pump regeneration in air dehumidification. The transcritical carbon dioxide heat pump and the dehumidification rotating wheel are combined, an evaporator of the transcritical carbon dioxide heat pump and the dehumidification rotating wheel are used for condensation and rotating wheel combined dehumidification on wet air, meanwhile, high-temperature heat energy of the transcritical carbon dioxide heat pump is used for heating rotating wheel regeneration air, and deep dehumidification in the high-humidity environment is achieved; the problems that a traditional dehumidification system is insufficient in efficiency and low in coupling performance are effectively solved.

Description

technical field [0001] The invention relates to the technical field of deep dehumidification, in particular to a composite dehumidification system and application based on transcritical carbon dioxide heat pump regeneration. Background technique [0002] A heat pump is a device that can efficiently collect heat and transfer heat. It consumes a small amount of high-grade energy and then thermally circulates it to move the heat from low temperature to medium high temperature. It has obvious energy-saving effect and is of great significance for the rational use of energy. The transcritical carbon dioxide heat pump, because of its transcritical cycle characteristics, has the characteristics of large temperature glide, and has a performance that surpasses the conventional heat pump in supplying high temperature heat energy. [0003] In the air, the volume ratio of water vapor is generally 0.01% to 0.03%. Although the water vapor content is very low, the humidity greatly affects t...
